Description

technical field

[0001] The invention relates to a digestion device in chemical analysis instruments in the field of environmental protection, in particular to a high-temperature and high-pressure closed digestion device. Background technique

[0002] The high temperature and high pressure airtight digestion device of the present invention is mainly used in chemical analysis instruments to realize high temperature and high pressure airtight digestion. The existing digestion heating methods are mainly divided into three types: electric heating, microwave heating and infrared heating. Because microwave heating and infrared heating instruments and equipment are relatively complex and relatively expensive, most of the on-line analytical instruments currently use electric heating.

[0003] High temperature and high pressure digestion means high temperature closed digestion, which can speed up the reaction speed and improve the reaction efficiency. For example, in the determinati...
